Someone, please answer I´m in math and none of the classmates I know knows what to do. The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was $1,000? $5,000? $5,020? x $$dollars?
and can you explain, please

Answer: 3b + 4c = T

Since brownies are three dollars and cupcakes are four, we simply do the amount of items bought multiplied by three or four.

Hope this helps :)

Answer:

she can make 12 bracelets

Step-by-step explanation:

Step-by-step explanation:

m<ACB=m<CBD=90 degrees (given) and AB=DC (given)

BC=BC (reflexive property)

m<ABC=m<BCD (alternate interior angles)

triangle ABC is equivalent to triangle DCB by Angle Side Angle.

I think that's correct, I'm on this unit too.

Answer: The third option is correct

Answer:

  y = -0.50x -2.50

Step-by-step explanation:

The perpendicular line will have a slope that is the opposite reciprocal of the slope of the given line:

  m = -1/2

The given point can be used with this slope in the point-slope equation for a line:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y +5 = -1/2(x -5)

  y = -1/2x +5/2 -5

  y = -0.50x -2.50

Answer: It is one out of six

Answer: 6 years

Step-by-step explanation:

Let Maria's age be x

Jonathan is four times Maria's age. This means that Jonathan age = 4x

In 3 years, he will be three times as old as Maria is then. This can be written as:

4x + 3 = 3(x + 3)

4x + 3 = 3x + 9

4x - 3x = 9 - 3

x = 6

Maria is 6 years

Answer:

the answer is 5 5/8

Step-by-step explanation:

if you make 11 1/4 into an improper fraction, you get 45/4 (this fraction simplified would give you your original mixed number). Using the keep, change, flip rule, you would multiply 45/4 by 1/2, giving you 45/8. This fraction simplified is your answer, 5 5/8.

Answer:

b ≈ 4.2

Step-by-step explanation:

Using the tangent ratio in the right triangle, that is

tan50° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{5}{b}[/tex] ( multiply both sides by b )

b × tan50° = 5 ( divide both sides by tan50° )

b = [tex]\frac{5}{tan50}[/tex] ≈ 4.2 ( to the nearest tenth )

Answer:

352

Step-by-step explanation:

220 ÷ 100 = 2.2

2.2 x 60 = 132

132 + 220 = 352

I hope this helps, have a good day and stay safe! if this is right can i get a brainiest? :3

Answer:

Yes

Step-by-step explanation:

These are congruent because according to the angle sum theorem if at least two of the angles are the same then they would be considered congruent.

Answer:

The triangles are congruent by SSS.

Step-by-step explanation:

It is marked in the diagram that sides AD and BC have equal length, and sides AB and CD have equal length. Side AC is common to both the triangles. Since  [tex]\overline{AB} \cong \overline{CD}[/tex], [tex]\overline{BC} \cong \overline{AD}[/tex], and [tex]\overline{AC} \cong \overline{AC}[/tex], it follows from SSS (side-side-side) congruence that [tex]\triangle ABC \cong \triangle CDA[/tex].

Answer:

a) 614.8km

b) $185.25

Step-by-step explanation:

25L = 265km

58L = [tex]\frac{58}{25}[/tex] × 265km

       = 614.8km

To find the cost of the petrol used, we need to find the amount of petrol used for 1007km first. You already know 265km requires 25L of petrol based on the question.

265km = 25L

1007km = [tex]\frac{1007}{265}[/tex] × 25L

             = 95L

You also know for 1L, the cost is $1.95. Thus, you can find the cost for 95L.

1L = $1.95

95L = 95 × $1.95

      = $185.25

Answer:

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex ad a is a multiplier

Here (h, k ) = (8, - 1 ) , then

y = a(x - 8)² - 1

To find a substitute (0, - 17 ) into the equation

- 17 = a(0 - 8)² - 1 ( add 1 to both sides )

- 16 = 64a ( divide both sides by 64 )

[tex]\frac{-16}{64}[/tex] = a , that is

a = - [tex]\frac{1}{4}[/tex]

y = - [tex]\frac{1}{4}[/tex](x - 8)² - 1 ← equation of parabola

Answer:

15-ounce package is the best buy.

Step-by-step explanation:

In order to find the best-buy we have to calculate the price per ounce.

So,

For 7-ounce package:

Price =2.45$

Unit price for 7-ounce:

[tex]\frac{2.45}{7} = 0.35\$[/tex]

For 15-ounce Package:

Price: $4.95

Unit price for 15-ounce:

[tex]\frac{4.95}{15} = 0.33\$[/tex]

For 26-ounce Package:

Price: $8.84

Unit price for 26-ounce:

[tex]\frac{8.84}{26} = 0.34\$[/tex]

As we can see that the least unit price is for 15 ounce pack i.e. 0.33 per ounce so,

15-ounce package is the best buy.

Answer:

8 miles an hour

Step-by-step explanation:

Btw that is one slow car.

Please mark brainliest.

Answer:

8 m/h

Step-by-step explanation:

In order to solve this, first understand that miles per hour is represented as [tex]\frac{miles}{hour}[/tex] So if there are 32 miles in 4 hours, then [tex]\frac{32m}{4h}[/tex] is your answer. Now 32/4 can be be simplified. The simplified version is 8 m/h.

Answer:

45 cups

Step-by-step explanation:

15x3 because there are 3 cups and 15 is one of the cups so 15x3=45

Answer:

45 Cups

Step-by-step explanation:

Use a proportion with cups in the numerator and pail in the denominator .

15/(1/3) = X/ 1

15 ÷1\3 = 15 x 3 =45 cups

Answer:

36

Step-by-step explanation:

Find the rule for the sequence.

The change from 1 to 3 is +2.

The change from 3 to 6 is +3.

The change from 6 to 10 is + 4.

The change from 10 to 15 is + 5

Essentially, you are adding 1 and then adding it to the current number. The next 3 numbers are:

Change of +6: 15 + 6 = 21

Change of +7: 21 + 7 = 28

Change of +8: 28 + 8 = 36

36 is your 8th term.

Answer:

Geometric sequence

.Step-by-step explanation:

Geometric sequences are defined by an initial value and a common ratio . If a sequence does not have a common ratio or a common difference, it is neither an arithmetic nor a geometric sequence. You should still try to figure out the pattern and come up with a formula that describes it.

Answer:

[tex]Perimeter = 12 + 6y[/tex]

Step-by-step explanation:

Represent the length with x and width with y

By analysis, we have:

Length = 6 + 2 times the width.

Mathematically, the expression is:

[tex]x = 6 + 2 * y[/tex]

[tex]x = 6 + 2 y[/tex]

Required: Determine the perimeter

Perimeter of a rectangle is calculated as:

[tex]Perimeter = 2 * (Length + Width)[/tex]

Substitute x for length and y for width

[tex]Perimeter = 2 * (x + y)[/tex]

Substitute 6 + 2y for x

[tex]Perimeter = 2 * (6 + 2y + y)[/tex]

[tex]Perimeter = 2 * (6 + 3y)[/tex]

Open bracket

[tex]Perimeter = 2 * 6 + 2 * 3y[/tex]

[tex]Perimeter = 12 + 6y[/tex]

you will have 8 hours in each part.
